She and her husband, John Trimble, assisted Gene Roddenberry in setting up Lincoln Enterprises and were put in charge of answering the deluge of fan mail. She edited newsletters, wrote articles in many zines, and started the letter-writing campaign called Star Trek Lives! to bring the show back after it had been threatened with cancellation. Trimble also created The Star Trek Concordance with Dorothy Jones Heydt.
She talks about her experiences in the book On The Good Ship Enterprise: My 15 Years With Star Trek, published in 1983.
Trimble, never shy about her role in Star Trek history, used it to promote interest in her later publications: from flyers for Space-Time Continuum: "Edited by the original 'SAVE STAR TREK' lady, Bjo Trimble" and "from Bjo Trimble, the fan who saved Star Trek."
Between April 1980 and April 1983, Trimble was a regular columnist in Starlog for a series called "Fan Scene." Some examples Fan Scene: Introducing Bjo #33 (April 1980), How to Win in a Walk... Across the Masquerade Stage #50 (September 1981) and Bjo-Con 1 #68 (March 1983).
Trimble coined the term Dippie, a term she used to describe a foolish and shrill Star Trek fan.

1993: A Fan Wishes Her a Happy Birthday
The 15th August 1993 sees the 60th birthday of a pretty special person in fandom, Bjo Trimble. Bjo has been a friend and mentor to me for a long time, and I grew up knowing she was a special person whose energy and talents have touched more people than some meet in a whole lifetime. Yet, new fans barely recognise the name. Now, I can live without Australian neofans not knowing who Sue Clarke is, but not knowing who Bjo Trimble is is like saying you don't know who the Father of Federation is, or who the first man was who walked on the Moon.
Without Bjo's efforts, there would not have been a third season of Star Trek, or the first of the Trek movies which lead to the rest, and the new series. Did you realise that she manned the orders that went out to you through the Federation Trading Post, or answered your enquiries sent to Gene Roddenbery [sic] in those earlier years; or that she is the penultimate Trek expert in the world? That she was in the first of the Trek movies, or that Gene Rodenbery [sic] and Harvey Bennet [sic] introduce her as one of the most important people to know? That she was one of the founding members of the Society of Creative Anachronism which has branches all over the world; or that worked as a clown-helper in those first Special Olympics?If you can get a copy of her book ON THE GOOD SHIP ENTERPRISE, you'll see what I mean and get an appreciation of the energy, generosity and creativity of this powerhouse of a woman.
